CHARLES A. L. SAUNDERS, OF ELGIN, ILLINOIS.

SCOURING-WHEEL OR THE LIKE.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed August 9.1906. Serial No. 329,806.

To all whom it may concern:

Be it known that 1, CHARLES A. L. SAUNDERS, a citizen of the UnitedStates, residing at Elgin. county of Kane, and State of Illinois, haveinvented certain new and useful Improvements in Scouring-Wheels or theLike, of which the following is a description.

My invention relates to grinding, polishing, or abrading wheels, inwhich the abradiug material is so mounted upon the wheel that it may beremoved and a new surface substituted when desired without damage to thewheel body.

The object of my invention is to provide a simple mmvenient andeconomical device of the kind described and one in which if desiredsufficient surface material may be stored within the wheel to renew theabrading surface a number of times with comparatively no loss of time ormaterial.

To this end my invention consists in the novel construction,arrangement, and combination of parts herein shown and described andmore particularly pointed out in the claims.

In the accompanying drawings wherein like or similar referencecharacters indicate like or corresponding parts; Figure l is anelevation of 'my device. Fig. 2 is a section taken substantially on line2-2 of Fig. 3. Fig. 3 is a section taken substantially on line 3-3 ofFig. 2. Fig. 4 is a section taken substantially on line 1*4 of Fig. 5showing a slightly modified form of my device. Fig. 5 is a section takensubstantially 011 line 5-5 of Fig. l; and Fig. (i is an elevation of theform shown in Figs. 4 and 5. 1

My device consists ordinarily of a hollow wheel provided with means formounting the same upon a shaft when in use and about the periphery ofwhich a strip of sand-paper, emery-cloth, or other suitable abradingmaterial may be tightly drawn with its ends firmly secured within thewheel.

In the form of my device shown in the drawings the wheel consistspreferably of the parts 1. and 2 inclosing a chamber 3 between them, thechamber being shown principally in the part 1 with the part 2 servingmerely as a cover attached to the part 1 by screws 4- 1. or othersuitable means so that the parts will not become separated or misplacedwhen not in use.

Any suitable means may be provided for mounting my device upon a shait,or mandrel. As shown hubs 5-5 are provided upon the parts 1 and 2 with acentral opening 15 of suitable size to receive the shaft, and setscrews6-6 or other suitable means for rigidly securing the same to the shaft.

The chamber 3 may be of any desired form but is preferably circular,concentric with the wheel, and slightly deeper than the width of theflexible strip or sheet of abrading material 7 used upon the wheel. Aslot 8 extends from the chamber 3 to the periphery of the wheel and therim at each side ofthe slot is slightly l l l l rounded or at least thesharp corner removed to prevent injury to the strip 7 when tightly drawnabout the wheel with both ends extending through the slot into thechamber 3.

Any suitable means may be provided within the chamber 3 forsecuring theends of the strip 7. Asshown two spindles 9 and 9 each provided with apart 14. adapted to be engaged by a wrench or equivalent means arerotatably mounted upon the parts .I and 2 extending across the chamber 3parallel with the axis of the wheel, that part of each spindle within.the chamber 3 being provided with a slot 10 or other suitable means forpositively engaging the strip 7 which may be looped as shown in Fig. 3or otherwise arranged to provide a positive attachment with thespindles. A ratchet wheel 11 is provided upon each spindle and a springactuated pawl 12 for each ratchet is mounted upon the part 1 in positionto cooperate with the ratchet to normally control the direction ofrotation of each spindle. When so arranged it is obvious that eachspindle may be employed both as a winch to tightly draw the strip 7about the periphery of the wheel and also as a reel upon which aconsiderable length of the strip 7 may be stored so that, when theabrading material exposed upon the wheel becomes worn and requiresrenewal the spindles may be oper ated to unwind or give out a portion ofthe unused strip stored within the chamber and draw in that which hasbecome worn to renew the abrading surface of the wheel without openingthe chamber or waste of material as the end of the worn portion of thestrip 7 may be brought just to the slot and thus wear out every portionof the strip.

Obviously in the above described manner all of the abrading surface ofthe strip 7 may be fully used except that part at each end extendingfrom each spindle to the periphery of the wheel at the slot and in theform shown a strap or end 20 of suitable length to reach from the slotto the spindle and provided with suitable means for engaging the spindleis attached to each end of the strip 7 so that every part of theabrading strip may be used.

In Figs. 1 and 3 a pad or cushion consisting of a ring 16 of leather issecured directly to the periphery of the wheel a ring 17 of felt outsideof, and secured to the leather affording a soft and slightly yieldingbacking for the strip 7. When thus prepared the wheel is especiallydesirable as a scouring wheel for use upon leather goods or for anypurpose where a slightly yielding surface is desirable.

In Figs. 1 to 6 a slightly modified form of my device is shown in whichthe ratchets l1 and pawls 12 are positioned within the chamber 3preferably in recesses l818 formed in the member 1; and openings 19-19are provided to afford access to the pawls so that either spindle may berotated to unwind the strip 7 if desired.

In this form also the cushions 16 and 17 are omitted and the strip 7 isdrawndown directly upon the periphery of the wheel.

Obviously however if desired a cushion similarto that described or ofany desired construction may be employed with the form of wheel shown inFigs. 4 to 6 or other slight modifications may be made in my devicewithout departing from the spirit of my invention, hence I do not wishto be understood as limiting myself to the exact form or constructionshown.

What i claim as new, and desire to secure by Letters Patent is:

1. A device of the kind described, comprising a wheel provided with achamber, and a slot extending from said chamber to the periphery of thewheel, in combination with a pair of rotatable spindles positionedwithin said chamber, and each attached to one side only of said wheel,means for rotating said spindles, means to normally prevent saidspindles from rotating in one direction, and means for attaching saidwheel in position.

2. A device of the kind described, comprising a wheel provided with achamber, and a slot extending from said chamber to the periphery of thewheel, in combination with rotatable spindles positioned within saidchamber each spindle permanently attached to one side only of said wheeland loosely supported in the opposite side means for attaching aflexible strip to each spindle, means for rotating said spindles, meansto normally control the direction of rotation oi said spindles, andmeans for attaching said wheel in position.

In a device of the kind described, a wheel provided with a chamber, anda slot extending from said chamber to the periphery of the wheel, incombination with a plurality 01 rotatable spindles extending across saidchamber, each spindle permanently secured to one wall only 01 said wheeland adapted to carry a roll of flexible material, means for said spindlefor positively engaging one end of said flexible strip, a ratchet andpawl for each spindle, positioned within the chamber for controlling thedirection of rotation of the spindles, and means for engaging saidspindles to rotate the same.

4. In a device of the kind described, a two part wheel having a chamberbetween the parts with a slot extending to the periphery of the wheel, apair of spindles rotatably attached to one part only of said wheel, eachspindle adapted to support a roll of flexible material within thechamber, and means for controlling the positions of said spindles.

5. In a device of the kind described, a two part wheel comprising arecessed part, and a flat part adapted to close the open side of saidrecess, said recessed part having a slot extending from said recess tothe periphery of the wheel, in combination with a plurality of rotatablespindles extending across said recess, each attached to the flat partonly of said wheel, with means in the recessed part for looselysupporting the free end of said spindles, and means to control thedirection of rotation of said spindles.

In testimony whereof, I have hereunto signed my name in the presence of.two subscribing witnesses.
